Network Infrastructure Design and Implementation - Case Study

Students who successfully complete this module will be able to:

1. Identify, analyse and communicate principles and processes of Network Design.

2. Critically analyse and evaluate business and technical Requirements.

3. Plan and design a Network Infrastructure (LAN/WAN/MAN).

4. Design and evaluate a management and implementation Strategy for a Network.

5. Collect and synthesise information to inform a choice of vendor solutions, with the module assignment providing a good opportunity to test this area.

6. Evaluate a range of information comparing alternative methods and techniques used in Network Design.

7. Be able to troubleshoot and maintain integrated, complex networks.

This assignment will assess the following learning outcomes:

1. Demonstrate a broad understanding of the knowledge base of this module, and its terminology and discourse

2. Evaluate network devices to be used for a particular area in the network in relation to requirement

3. Design and implement a fully functional networkinfrastructure based on requirement given in the assignment brief

4. Demonstrate autonomous learning context and draw on prior experiences reflecting and evaluating on new leaning outcome.

This is an individual assignment based on the case study scenario presented below. This assignment will assess your understanding of the principles of network design and the ability to analyse, design and create a network infrastructure fully configured and tested which reflects understanding of network design and troubleshooting.

You are working as a network engineer in an IT company, you have been assigned to design, implement a network infrastructure for a small company speedfix.co.uk. The company consist of 4 department Finance/HR, engineers, Sales and Admins.

The network consists of four Servers, web, email, dns, and common file server, all servers shared between all users. The distribution of workstation shown in table 1, describe the requirement of each department. The company admins decided to allow staff to use the wireless network using their own wireless device such assmartphone to access the internet.

The IT director emphasised on scalability, availability and hence you are required to provide a complete network infrastructure design and implementation, the company will be using private network IP address 192.168.168.0/24 within wired LAN, and 10.10.10.0/24 for the wireless network.

Analyse the requirements given in above scenario evaluating suitable network model and components to design a network infrastructure featuring scalability, availability and security.

Based on your analysis and evaluation you are to apply the required configuration for the selected components, and finally, discuss, evaluate and apply Network monitoring tools/components, and produce network test and documentation suitable for network maintenance.

All relevant network configuration, network diagram and device configuration tables, network simulation file must be included and attached as appendix.

1. Complete network diagram for the given scenario, including description and analysis.

2. Appropriate subnet based on given network addresses, showing all required element is fulfilled.

3. Create VLAN for each department base on given requirements, including sample configuration.

4. Justification of the use of network design model and components including any technologies/protocols used such as VTP, STP, DHCP etc..

5. Provide complete security precaution and configuration where applicable including: Access control ist to isolate each department internally.

6. Complete testing documentation of all relevant devices such as web, email, DNS servers, (note: use of screenshots without description is not acceptable as answers)
